REGISTRATION
NOTICE:
The Vehicle Identification Number (VIN) must be input
into the replacement ECM.
HINT:
The VIN is a 17-digit alphanumeric number. The intelligent
tester is required to register the VIN.
1. DESCRIPTION
This registration section consists of 3 parts: Input
Instructions, Read VIN and Write VIN.
(a) Input Instructions: Explains the general VIN input
instructions when using the intelligent tester.
(b) Read VIN: Explains the VIN reading process in a
flowchart. This process allows the VIN stored in the
ECM to be read in order to confirm that the two
VINs, provided with the vehicle and stored in the
vehicle's ECM, are the same.
(c) Write VIN: Explains the VIN writing process in a
flowchart. This process allows the VIN to be input
into the ECM. If the ECM is changed, or the vehicle
VIN and ECM VIN do not match, the VIN can be
registered or overwritten in the ECM by following
this procedure.
2. INPUT INSTRUCTIONS
(a) Intelligent Tester
The arrow buttons (UP, DOWN, RIGHT and LEFT)
and numerical buttons (0 to 9) are used to input the
VIN.
(b) Cursor Operation
To move the cursor around the tester screen, press
the RIGHT and LEFT buttons.
(c) Alphabetical Character Input
(1) Press the UP and DOWN buttons to select the
desired alphabetical character.
(2) After selection, the cursor should move.
(d) Numeric Character Input
(1) Press the numerical button corresponding to
the number that you want to input.
(2) After input, the cursor should move.
HINT:
Numerical characters can also be selected by
using the UP and DOWN buttons.
(e) Correction
(1) When correcting the input character(s), put the
cursor onto the character using the RIGHT and
LEFT buttons.
(2) Select or input the correct character using the
UP/DOWN buttons, or the numerical buttons.
(f) Finishing Input Operation
(1) Make sure that the input VIN matches the
vehicle VIN after input.
(2) Press the ENTER button on the tester.

3. READ VIN
(a) Confirm the vehicle VIN.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn the tester ON.
(e) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / VIN.
4. WRITE VIN
(a) Confirm the vehicle VIN.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn the tester ON.

CHECKING MONITOR STATUS
The purpose of the monitor result (mode 06) is to allow
access to the results of on-board diagnostic monitoring tests
of specific components/systems that are not continuously
monitored. Examples are catalysts, evaporative emissions
(EVAP) and thermostats.
The monitor result allows the OBD II scan tool to display the
monitor status, test value, minimum test limit and maximum
test limit. These data are displayed after the vehicle has been
driven to run the monitor.
When the test value is not between the minimum and
maximum test limits, the ECM (PCM) interprets this as a
malfunction. If the test value is on the borderline of the test
limits, the component is likely to malfunction in the near
future.
Perform the following procedures to view the monitor status.
Although these procedures refer to the Lexus/Toyota
diagnostic tester, the monitor status can be checked using a
generic OBD II scan tool. Refer to your scan tool operator's
manual for specific procedural information.
1. PERFORM MONITOR DRIVE PATTERN
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch and the tester ON.
(c) Clear the DTCs (see page ES-39).
(d) Run the vehicle in accordance with the applicable
drive pattern described in READINESS MONITOR
DRIVE PATTERN (see page ES-22). Do not turn the
ignition switch OFF.
NOTE:
The test results will be lost if the ignition
switch is turned OFF.
2. ACCESS MONITOR RESULT
(a) Select the following items from the intelligent tester
menus: DIAGNOSIS, ENHANCED OBD II,
MONITOR INFO and MONITOR RESULT. The
monitor status appears after the component name.
• INCMP: The component has not been monitored
yet.
• PASS: The component is functioning normally.
• FAIL: The component is malfunctioning.
(b) Confirm that the component is either PASS or FAIL.
(c) Select the component and press ENTER. The
accuracy test value appears if the monitor status is
either PASS or FAIL.
3. CHECK COMPONENT STATUS
(a) Compare the test value with the minimum test limit
(MIN LIMIT) and maximum test limit (MAX LIMIT).

(b) If the test value is between the minimum and
maximum test limits, the component is functioning
normally. If not, the component is malfunctioning.
The test value is usually not near the test limits. If
the test value is on the borderline of the test limits,
the component is likely to malfunction in the near
future.
HINT:
The monitor result might on rare occasions be
PASS even if the malfunction indicator lamp (MIL) is
illuminated. This indicates the system malfunctioned
on a previous driving cycle. This might be caused by
an intermittent problem.

the scaling value listed below.
